I have a serious problem with Admob that prevent me from releasing my game on the play store.
When i was creating my game and testing it other directly on my phone and phones of my friends by USB, ads where correctly showing, in "test device mode" with test ads and with the real ads.
But when i released a beta version on the play store, the ads stopped to be displayed, if i try to make another APK with the same package name of my released app, admob will not display the ads and return an error "error code" without any code. But if i change the package name, everything is showing up again!
Anybody know what's going wrong with Admob?
